🛠️ How to Setup & Install This MCP Server

1. Prerequisite Installation & Python Virtual Environment Setup

1. Open PowerShell or Terminal in the project directory:

   cd "d:\Studio\MCP -Storywriting"

2. Create and activate a Python virtual environment:

   python -m venv venv
   .\venv\Scripts\Activate.ps1

3. Install required packages:

   pip install -r requirements.txt

2. Setting Up in Claude Code / Claude Web (Remote Connector via Ngrok)

To connect Claude Web / Claude Code to your local MCP server:

Step 2A: One-Time Ngrok Authtoken Setup

Authenticate ngrok to resolve remote connection errors:

ngrok config add-authtoken <your-ngrok-authtoken>

Step 2B: Start the MCP Server in Streamable HTTP Mode

Run the server on port 8000:

& "d:\Studio\MCP -Storywriting\venv\Scripts\python.exe" server.py --transport streamable-http --port 8000

(Keep this terminal open!)

Step 2C: Start Ngrok HTTPS Tunnel

In a second terminal window, start ngrok:

ngrok http 8000

Copy the generated https:// forwarding URL (e.g. https://a1b2-34-56-78-90.ngrok-free.app) and append /mcp: $$\rightarrow \text{\texttt{https://a1b2-34-56-78-90.ngrok-free.app/mcp}}$$

Step 2D: Configure Claude Connector UI

1. In Claude Web or Claude Code, open Add custom connector.

2. Set:

   • Name: Storywriting & Screenplay Engine

   • Remote MCP server URL: https://a1b2-34-56-78-90.ngrok-free.app/mcp

3. Click Save / Connect. All 67 tools, 4 resources, and 2 prompts will be instantly available in Claude!

3. Setting Up in ChatGPT (GPT-4o)

You can use this MCP server with ChatGPT (GPT-4o / O3-mini) in two easy ways:

Option A: Inside Cursor / Antigravity / Windsurf IDEs (Recommended)

1. In your IDE MCP settings, add:

   {
     "mcpServers": {
       "storywriting-engine": {
         "command": "d:\\Studio\\MCP -Storywriting\\venv\\Scripts\\python.exe",
         "args": ["d:\\Studio\\MCP -Storywriting\\server.py"]
       }
     }
   }

2. Select GPT-4o or o3-mini in the AI model dropdown.

3. ChatGPT will natively execute all 67 screenplay tools, draft prose, and render storyboards!

Option B: Via Open-WebUI / LibreChat / Custom GPT Actions

1. Launch the server in HTTP mode (server.py --transport streamable-http --port 8000).

2. Open Open-WebUI Settings $\rightarrow$ Tools $\rightarrow$ Add MCP Server URL: http://localhost:8000/mcp.

3. Select GPT-4o as your active LLM.

4. Live Integration with VS Code "Better Fountain" Extension

This server natively generates industry-standard Fountain 1.1 screenplay files (.story/screenplay.fountain).

1. Install the Better Fountain extension in VS Code.

2. Open d:\Studio\MCP -Storywriting\.story\screenplay.fountain.

3. Whenever Claude or the MCP engine commits screenplay scenes, Better Fountain instantly updates:

   • Live side-by-side formatted screenplay preview

   • Real-time page count and scene duration estimates

   • Interactive scene outline sidebar
